    i18n: ensure we setup i18n/l10n during application startup
    
    Historically, Sysprof never supported translations. When revamping the
    Sysprof implementation we didn't fix that, even though we were able to
    start accepting translations.
    
    This ensures we setup the translation tooling at startup.
    
    Fixes #3
